MULTIPLE-ENGRAVING MACHINE.

Application filed January 2, 1920. Serial No.'349,114.

To all 'wimm it concern: Y Y

Be it known that I, H. FAIOHNEY, a citizen of the United States. residing at V atertown, in the county of Jefferson and Stateof New York, have invented certain new and useful Improvements in Multiple-- Engraving ll lachines, of which the following is a'specification.

This invention relates to improvements 1n multi le engravin machines articuk. C) t 7 larly of the type employed for inscribing.

names, numbers and the like upon manufactured articles.

The object of theinvention is to provide a machine of the class, which may be controlled and actuated by any suitable pantographic mechanism, and which is arranged to engrave a plurality of articles in the same manner at the same time, by the ein ployment of a single operator. A further object is to provide a multiple engraver which is capable of simultaneously engraving articles of different size and shape, without requiring any special adjustment, or alteration or change of any of the parts of the machine, and wherein the graving or scribing may be effected on'flat, concave or convex surfaces, by means of self adjusting engraving tools. which are arranged to simultaneously gravitate to the engraving position, and to be'automatically released at the end of the engraving operations. vA- fnrther object is to provide. an uprightframe for upporting the engraving tools and related parts in vertical tiers,'the said frame adapted for universal movements in a horizontal plane by a simple connection with thepantograph mechanism. And a further object is to providea plurality of work-supporting members upon whichadjustable work holders are slidably mounted, the said members being disposed horizontallyone above the other-and each member arranged to adjust-ably support a number of articles to be engraved. I

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawings, in which 7 i V Figure 1 is a front. side elevation of the complete machine. Fig.2is an end elevation of the same. 7 ing a modified construction of certain parts of. the stationary frame. Fig, a top 3 is a view; showi planview of the machine, Fig. 5 is larged broken top face. view of one of the work supporting members; showinga pair of the adjustable work holders. Fig.6 is a cross-section, taken on line (S- 6 of Fig. 5. Fig, 7 is a view of one of the clinical thermometers; showing the numbers engravedv thereon by the machine. Fig. 8 is a view of v the barrel of a common hypodermic syringe,

which may beengraved at the same time the smaller caliber thermometers are engraved, where the matter is common to both articles. And Fig. 9 is an enlarged side elevation of one'of the engraving tools and itssupports;

The present machine comprises two upright frames, onestationary, the other movable, and the stationary frame preferably frame, upon which are rigidly mounted horizontal and transverse rails 3, the front ends of said rails beingtied together by a brace 3 Upon each rail Bus mounted a plurality of similar spaced posts 3, which alternate wlth similartransverse rails 3, the latter bemg; disposed in different hori-.

zontal planes, for supporting a number of an enhorizontal and longitudinal work-supporteach bar 4 is provided with a longitudinal 'dove-tail groove 4;, in whichis slidable a plurality of adjustable work holders 4 the latter comprising brackets whose bases con-- form to and are slidable in the groove 4'.

Each bracket is provided with-an upright lu 4 which is perforated to receive and hold the work. C. These lugs are also pro;-

vided with threaded perforations to receive I threaded connecting andadjusting'rods' l by which the said brackets be moved towardand away fromrach other and made to tightly grip and hold the work Q. The screws 4 are of sufiicient length to permit the handling of work of different lengths, as shown by the full and dotted lines in Figs. 1 and 5. Thebrackets or holders 1 preferably snugly fit in the grooves 1, so that no additional securing means, other than friction, is needed for holding them in the various adjusted positions. 7 V I 'The engravingis accomplished by a pin; rality of similar gravitative needles or tools 5, which are preferably arranged in horizontal rows, one above the other, the same as the bars 41. 'These' needles are supported and given their proper movements for effectingthe engrav ng bythe movable frame,- whlch Wlll now be described: 9-9 des1gnate similar elongated grooved members comprising two transversely arranged ballbearings,the members 9 being rigidly secured to the base 2; while the members 9 are allowed longitudinal -movements relatively to the members 9 by means of balls 9, which play in'the facin members. 101O 'designate similar grooved members of another pair of bearings, which 3 2 extend longitudinally through the machine,

at right angles to the bearings 9 L9, in 'whlch the members ll) are mountedon the tops of the members 9, and are rigidly se cured thereto by braces 10 the latter only shown in Fig. 2. Balls 10 are disposedin the facing grooves of the members 1010,

' and these halls'support'themembers 10,;and

allow them longitudinal movementsfinde pendently of the other members. The topmostmembers 10 aretiedtogether at their opposite ends by transverse cleats 109, which constitute the normal base of the movable frame. gUpon' the cleats 10 are correspondingly mounted columns 11-11 of equal reciprocably and rotatably mounted in the,

vertical arms of L-shaped hracketsfiflwhich are adjustably secured tothe bars 7 by bolts 6-, the latter passing through slots (Pin the horizontal arms, of said brackets and are threaded into the, bars 7. this means the needles 5are properly positioned Ti le-f. tively to the work C carried by the holders 4?. The plungers 6 are provided with fingers or arms 6, which extend at right angles to'their .top ends. These fingers nor mally rest npon thetop edges of siniilarl rocking-bars 12,'wh1ch are d1sposed horizon a tally above and parallel to the bars 1 and 7.

The rocking-bars 12 are journaled-in bearing blocks 12 and 12 which are supportedrespectively by theicolum ns 1 1-, 1-1 and the bars 7. The corresponding ends of the rockrooves of said ing bars 12 are fitted with similar wheels 12% which are tied together for simultaneous operation by a rod 12 the latter be.-

- ing operatively connected with a pedal 12 by a cord 12, a lever 12 and a link 1% (see Fig. 1). Therocking-bars12 control the vertical movements of the tools 5 and plungers 6,1and when thee-aid parts are 1n the full line position shown in Figs. t and 9,

the bars 1-2 sustain-the full weight of the plungers and needles, which are then in their upper or released positions. The bars 12 named position by a spring 13, one end of which is attached to the adjacent column 11, while its opposite end is connected to an arm 13" fixed to one of the wheels 12 (see Figs. 1 and for moving the bars 12 in the opposite direction to that of the pedal 12% g The movable frame, which supports the engraving needles 5, is actuated during the engraving operations by a Vpantographic mechanism, which'is controlled by the operator while he traces the copy A, which is reproduced by the needles on the work (1' The pantograph mechanism consists of a,

substantially horizontal tracer arm 14:, which supports at one end a -tracing'pencil or point 14; The arm l lj extends rearwardly "and passes beneath thestatio'naryand movable frames, and its rear end is pivoted to an 0s oillating upright lever 15,whose upper end is plvoted by. a bolt 15' in a horizontally disposed frame 16. The frame 16 is mount ed beneath astationary arch 17, which is rigid on the base '2, and the said frame is pivoted at 16, for certain rocking movements, to a bolt 17, which depends from thecenter of the arch. The pivots 16 allowthe frame 16 and the lever 15 to rock or oscillate like a pendulum, as indicated by the dotted lines in Fig. 1. The upright lever 15 alone is operatively connected to the movable frame by a rod one end l8of which is a yoke, which is connected to .the'lever 15 below the pivot 1-5, by pivots 18 ,The oppos te or outer end of the rod 18 is journaled in a bearing 19 which adjustablysup mrted by an inverted V-shaped brace 20, the latter being rigidly secured to the rearends of the cleats 10, and is .aremoved to and maintained inthe last The spring 13 exerts its-tension V therefore a part of the movable framc. The V fork'18 is adjustable vertically on the lever 15 for varying the movements of the movable fra'me a bolt 18 and a thumb-nut 18%, When .the operator moves the tracer arm ,14: forward and backward over the copy A the lever 15 moves correspondingly, and causes the rodg18 to move the needlesupporting frame 1n the same directions, as

indicated-by thedottod lines in Figs. 2 and 1- and during the said 0 oration. the whole .movable frame down to and includingvthe bearin members 9 artici ate in the said g P P I the balls as indicated by the dotted lines,

in Figs. 1 and 4. By these means the frame which actuates the engravers 5 is g ven substantially universal movements in a horizontal plane on the several ball bearings 9 and 10. These bearings exert so little friction, that'the movable frame readily responds to the tracer arm 14, and requires very little force or power to operate it. The movable parts of the machine are held in place upon the relatively long bearings 9 and 10 alone by gravity. I 5

The presentmachine is designed and con structed particularly for engraving the degree numbers on the thermometers C, and in order to properly carry out this work, it is essential that the thermometers which are of relatively" small caliber and transparent,

be placed between the operator and the light,

so that the operator may accurately note the position of the relatively fine graduations on the tubes C,and adjust the work C so that the numbers may be engraved directly oppo site the degree marks to which they refer. For these reasons, it is preferable to dispose the work, as well as the engraving needles in vertical tiers, as shown, sothat none of the mechanism intervenes between the work and the light, to interfere with the precise adjustment of the work 0, andthe close inspection of the workduring the engraving operations. V. V, In Fig. 3 I have shown a modification con- .sistingprincipally of substituting angular braces 21 for the front posts 3 ,ffor permit tingthe readyand convenient handling of I the work-supporting bars 4., The bars 4 in Fig. 3 are provided with depending studs 4, which are received in corresponding sockets formedin the rails 3, for holding the bars from accidentally shifting during the engraving operations. a In Fig. 7 is shown one of the thermometers which is graduated in the usual manner and then engraved with the degree numbers by the present machine. Fig.8 illustrates the barrel C of the usual hypodermic ,syr inge, the same being of larger caliber than the thermometer, and which may be inserted in the ma'ohine and engraved with suitable matter common to-both kinds of work, without requiring any adjustment of the parts. When the barrels C are placed in the ma chine, a centering .part 22 is usually inserted in the mouth of the barrel, and its free end theninserted in the regular perforationin of the thermometers.

the lugof the holder, which takes one end In case some of the thermometers are of larger diameter than the others, the needles 5 merely gravitate a less distance in order to come into engraving contact with the work.

Obviously, some changes or modifications may be made in the parts of the machine, and that the number of the work-supporting bars 4, as well as of the needles 5and related parts may be increased or diminished, as compared with what is shown herein, without departing from the spirit of the inven tion.
